French–Spanish colonial era La Nouvelle-Orléans (New Orleans) was founded in the spring of 1718 by the French
Mississippi Company under
Jean-Baptiste Le Moyne de Bienville, on land traditionally inhabited by the
Chitimacha people. The city was named for
Philippe II, Duke of Orléans, then-regent of the
Kingdom of France whose title derived from the French city of
Orléans. Governor
Étienne Perier launched a retaliatory campaign that effectively destroyed the
Natchez people, but it soured relations between France and the territory's Native Americans leading directly into the
Chickasaw Wars of the 1730s. Native resistance continued into the 1740s under governor
Pierre de Rigaud, marquis de Vaudreuil-Cavagnial, as tribes including the
Chickasaw and
Choctaw leveraged competing colonial interests. Raids intensified as French economic instability weakened colonial defenses, with some Chickasaw attacks reaching as far south as
Baton Rouge. Meanwhile, labor shortages led the French colonists to turn to the
Atlantic slave trade. By the early 1720s,
enslaved Africans were arriving in significant numbers, and in 1724, the
Code Noir formalized harsh laws governing their lives. A distinct Afro-Creole culture began to develop, blending African traditions with Catholicism and French language, giving rise to practices such as
Louisiana Voodoo and the
Louisiana Creole language. New Orleans quickly emerged as a cultural and commercial hub in French Louisiana. Its position as a key port made it the gateway for goods moving between the interior of North America and the Atlantic world. Institutions like the
Ursuline sisters, founded in 1727 by nuns sponsored by the
Company of the Indies, reflected the city's integration into French religious and educational networks. The convent educated girls and remains foundational to several modern schools in the city. Early city planning and architecture were shaped by military engineers like Pierre Le Blond de Tour and
Adrien de Pauger, whose designs laid out the enduring street grid and fortifications. By the 1740s, public works programs under engineer Ignace François Broutin transformed the city's architecture, blending colonial governance with a distinct Creole character. After France ceded Louisiana to the
Spanish Empire in the
1763 Treaty of Paris, New Orleans residents resisted Spanish rule. Local residents staged the
Louisiana Rebellion of 1768, briefly seizing control of the city and sending a delegation to France to appeal for renewed French authority. Their efforts failed, and King
Louis XV reaffirmed Spanish sovereignty. Nearly all of the surviving 18th-century
architecture of the Vieux Carré (
French Quarter) dates from the Spanish period, notably excepting the
Old Ursuline Convent. During the
American Revolutionary War, New Orleans played a key role as a supply hub for the American cause, particularly under Spanish governor
Bernardo de Gálvez y Madrid, Count of Gálvez, who led a campaign against the British from the city in 1779. From the 1760s onward,
Filipinos also began settling in the region.
United States territorial era (now Jackson Square), New Orleans, after the
Louisiana Purchase, marking the transfer of sovereignty over French Louisiana to the United States, December 20, 1803 The
Third Treaty of San Ildefonso in 1800 restored
French control of New Orleans and Louisiana, but
Napoleon sold both to the United States in the
Louisiana Purchase in 1803. Thereafter, the city grew rapidly with influxes of Americans,
French,
Creoles and
Africans. Later immigrants were
Irish,
Germans,
Poles and
Italians. Major
commodity crops of
sugar and
cotton were cultivated with
slave labor on nearby large
plantations. Between 1791 and 1810, thousands of
St. Dominican refugees from the
Haitian Revolution, both
whites and
free people of color (
affranchis or
gens de couleur libres), arrived in New Orleans; a number brought their slaves with them, many of whom were native Africans or of full-blood descent. While Governor
Claiborne and other officials wanted to keep out additional
free black people, the French Creoles wanted to increase the French-speaking population. In addition to bolstering the territory's French-speaking population, these refugees had a significant impact on the culture of Louisiana, including developing its sugar industry and cultural institutions. As more refugees were allowed into the
Territory of Orleans,
St. Dominican refugees who had first gone to
Cuba also arrived.
Slave rebellion On January 8–11, 1811, about 500 enslaved Africans in St. Charles and St. John the Baptist parishes rose up in the
German Coast rebellion against their enslavers, killing two white men in the process. They proceeded to march south toward New Orleans and were eventually controlled by the local militia, with numerous casualties on both sides. The uprising has been called the "largest slave rebellion in US history."
Battle of New Orleans and antebellum period During the final campaign of the
War of 1812, the British sent a force of 11,000 in an attempt to capture New Orleans. Despite great challenges, General
Andrew Jackson, with support from the U.S. Navy, successfully cobbled together a force of
militia from Louisiana and
Mississippi, U.S. Army regulars, a large contingent of
Tennessee state militia,
Kentucky frontiersmen and local
privateers (the latter led by the pirate
Jean Lafitte), to decisively defeat the British in the
Battle of New Orleans on January 8, 1815. at New Orleans, 1853 As a
port, New Orleans played a major role during the
antebellum period in the
Atlantic slave trade. The port handled commodities for export from the interior and imported goods from other countries, which were warehoused and transferred in New Orleans to smaller vessels and distributed along the Mississippi River watershed. The river was filled with steamboats, flatboats and sailing ships. Despite its role in the
slave trade, New Orleans at the time also had the largest and most prosperous community of free persons of color in the nation, who were often educated, middle-class property owners. New Orleans housed the largest slave market in the country, particularly after the U.S. ended the international slave trade in 1808. The domestic trade surged, with two-thirds of more than a million enslaved people forcibly relocated to the
Deep South. The trade's economic value was immense as slaves were collectively valued at half a billion dollars, and the broader economy surrounding the trade, including transport and services, generated billions more. As a result, New Orleans benefited significantly, both financially and commercially, from this system. Following the Louisiana Purchase, Anglo-Americans and later German and Irish immigrants migrated to the city, contributing to its rapid growth. The white Francophone population remained influential, with French still used in some schools. Free people of color (
gens de couleur libres), mostly of mixed race and largely Francophone, formed a distinct artisan and professional class, even as the majority of black residents remained enslaved. The city's prosperity was shadowed by repeated
epidemics of
yellow fever and other tropical and
infectious diseases, which killed over 150,000 residents in the 19th century. By 1860, the city's population had reached nearly 170,000, its per capita income was the second highest in the nation, and it was the third-largest U.S. port by import tonnage.
Civil War–Reconstruction era As the Creole elite feared, the
American Civil War changed their world. In April 1862, following the city's occupation by the Union Navy after the
Battle of Forts Jackson and St. Philip,
Gen. Benjamin F. Butler – a respected Massachusetts lawyer serving in that state's militia – was appointed military governor. New Orleans residents supportive of the Confederacy nicknamed him "Beast" Butler, because of an order he issued. After his troops had been assaulted and harassed in the streets by women still loyal to the Confederate cause, his order warned that such future occurrences would result in his men treating such women as those "plying their avocation in the streets", implying that they would treat the women like prostitutes. Accounts of this spread widely. He also came to be called "Spoons" Butler because of the alleged looting that his troops did while occupying the city, during which time he himself supposedly pilfered silver flatware. Significantly, Butler abolished French-language instruction in city schools. Statewide measures in 1864 and, after the war, 1868 further strengthened the English-only policy imposed by federal representatives. With the predominance of English speakers, that language had already become dominant in business and government. By the end of the 19th century, French usage had faded. It was also under pressure from Irish, Italian and German immigrants. However, as late as 1902 "one-fourth of the population of the city spoke French in ordinary daily intercourse, while another two-fourths was able to understand the language perfectly," and as late as 1945, many elderly Creole women spoke no English. The last major French language newspaper, ''
L'Abeille de la Nouvelle-Orléans (New Orleans Bee), ceased publication on December 27, 1923, after 96 years. According to some sources, Le Courrier de la Nouvelle Orléans'' continued until 1955. As the city was captured and occupied early in the war, it was spared the destruction through warfare suffered by many other cities of the
American South. The
Union Army eventually extended its control north along the
Mississippi River and along the coastal areas. As a result, most of the southern portion of Louisiana was originally exempted from the liberating provisions of the 1863
Emancipation Proclamation issued by President
Abraham Lincoln. Large numbers of rural ex-slaves and some free people of color from the city volunteered for the first regiments of Black troops in the War. Led by Brigadier General
Daniel Ullman (1810–1892), of the 78th Regiment of New York State Volunteers Militia, they were known as the "
Corps d'Afrique". While that name had been used by a militia before the war, that group was composed of
free people of color. The new group was made up mostly of former slaves. They were supplemented in the last two years of the War by newly organized
United States Colored Troops, who played an increasingly important part in the war. resting on cotton bales Violence in the South, including the
Memphis Riots and
New Orleans Riot of 1866, spurred Congress to pass the
Reconstruction Act and
Fourteenth Amendment, granting citizenship and civil rights to freedmen and free people of color. During Reconstruction, Louisiana and Texas were governed under the
Fifth Military District, and Louisiana was readmitted to the Union in 1868 with a new constitution that established
universal male suffrage, universal public education, and elected both black and white officials.
P.B.S. Pinchback briefly served as Louisiana's Republican governor in 1872, becoming the first U.S. governor of African descent. New Orleans also maintained a racially integrated
public school system during this period. However, wartime destruction, a financial recession, and the Panic of 1873 hindered economic recovery. From 1868, white insurgents used violence to suppress Black voters and disrupt Republican gatherings, culminating in the 1872 contested gubernatorial election and the rise of the "
White League", a paramilitary group supporting Democrats. In 1874, they seized state offices during the
Battle of Liberty Place, and by 1876,
Redeemers had reclaimed the state legislature. Federal troops withdrew in 1877, ending
Reconstruction. In 1892 the racially integrated unions of New Orleans led a
general strike in the city from November 8 to 12, shutting down the city & winning the vast majority of their demands.
Jim Crow era Dixiecrats and
Democrats passed
Jim Crow laws, establishing
racial segregation in public facilities. In 1889, the legislature passed a
constitutional amendment incorporating a "
grandfather clause" that effectively
disfranchised freedmen as well as the propertied people of color
manumitted before the war. Unable to vote, African Americans could not serve on juries or in local office, and were closed out of formal politics for generations. The Southern U.S. was ruled by a white Democratic Party. Public schools were racially segregated and remained so until 1960. New Orleans's large community of well-educated, often French-speaking
free persons of color (
gens de couleur libres), who had been free prior to the Civil War, fought against Jim Crow. They organized the
Comité des Citoyens (Citizens Committee) to work for civil rights. As part of their legal campaign, they recruited one of their own,
Homer Plessy, to test whether Louisiana's newly enacted Separate Car Act was constitutional. Plessy boarded a commuter train departing New Orleans for
Covington, Louisiana, sat in the car reserved for whites only, and was arrested. The case resulting from this incident,
Plessy v. Ferguson, was heard by the
U.S. Supreme Court in 1896. The court ruled that "
separate but equal" accommodations were constitutional, effectively upholding Jim Crow measures. In practice, African-American public schools and facilities were underfunded across the South. The Supreme Court ruling contributed to this period as the
nadir of race relations in the United States. The rate of
lynchings of black men was high across the South, as other states also disfranchised blacks and sought to impose Jim Crow. Nativist prejudices also surfaced.
Anti-Italian sentiment in 1891 contributed to the
lynchings of 11 Italians, some of whom had been acquitted of the murder of the police chief. Some were shot and killed in the jail where they were detained. It was the largest mass lynching in U.S. history. In July 1900 the city was swept by white mobs rioting after Robert Charles, a young African American, killed a policeman and temporarily escaped. The mob killed him and an estimated 20 other blacks; seven whites died in the days-long conflict, until a
state militia suppressed it.
20th century at Burgundy Street, looking lakewards (north) towards
Lake Pontchartrain in 1900 New Orleans's economic and population zenith in relation to other American cities occurred in the antebellum period. It was the nation's fifth-largest city in 1860 (after New York,
Philadelphia,
Boston and Baltimore) and was significantly larger than all other southern cities. From the mid-19th century onward rapid economic growth shifted to other areas, while New Orleans's relative importance steadily declined. The growth of railways and highways decreased river traffic, diverting goods to other transportation corridors and markets. It is also credited for the creation of the distinctly Louisianan
po' boy sandwich. By the mid-20th century, New Orleanians recognized that their city was no longer the leading urban area in the South. By 1950,
Houston,
Dallas, and
Atlanta exceeded New Orleans in size, and in 1960
Miami eclipsed New Orleans, even as the latter's population reached its historic peak. Georgia Institute of Technology president
Blake R. Van Leer defied the governor, and the game proceeded. The federal
Civil Rights Act of 1964 and the
Voting Rights Act of 1965 restored key constitutional protections, but economic and educational disparities between Black and White residents remained. As more affluent residents left the city, its population became increasingly poor and predominantly African-American. Beginning in 1980, Black-majority leadership emerged, working to address entrenched socioeconomic inequities. By the late 20th century, New Orleans had grown increasingly reliant on tourism amid rising poverty, low educational attainment, and high crime, which hindered its adaptation to the broader U.S. shift toward a post-industrial service economy. Although the city had always faced flooding risks, awareness of its vulnerability grew after
Hurricane Betsy in 1965 and the
May 8th 1995 Louisiana Flood. These events exposed the limits of the drainage system, prompting upgrades. By the 1980s and 1990s, scientists warned that
erosion of the marshlands and swamp surrounding New Orleans, exacerbated by developments like the
Mississippi River–Gulf Outlet Canal, had left the city more exposed than ever to hurricane
storm surges.
21st century at its landfall near the Louisiana-Mississippi border New Orleans was catastrophically affected by what Raymond B. Seed called "the worst engineering disaster in the world since
Chernobyl", when
the federal levee system failed during
Hurricane Katrina on August 29, 2005. By the time the hurricane approached the city on August 29, 2005, most residents had evacuated. As the hurricane passed through the
Gulf Coast region that day, the city's
federal flood protection system failed, resulting in the worst
civil engineering disaster in American history at the time. Floodwalls and
levees constructed by the
United States Army Corps of Engineers failed below design specifications and 80% of the city flooded. Tens of thousands of residents who had remained were rescued or otherwise made their way to shelters of last resort at the
Louisiana Superdome or the
New Orleans Morial Convention Center. More than 1,500 people were recorded as having died in Louisiana, most in New Orleans, while others remain unaccounted for. Before Hurricane Katrina, the city called for the first mandatory evacuation in its history, to be followed by another mandatory evacuation three years later with
Hurricane Gustav. The city was declared off-limits to residents while efforts to clean up after
Hurricane Katrina began. The approach of
Hurricane Rita in September 2005 caused repopulation efforts to be postponed, and the
Lower Ninth Ward was reflooded by Rita's storm surge. Ten years after the hurricane, the population had recovered to 80% of what it was at the 2000 census. Several major tourist events and other forms of revenue for the city have returned. Large conventions returned. College bowl games returned for the
2006–2007 season. The
New Orleans Saints returned that season. The
New Orleans Hornets (now named the Pelicans) returned to the city for the
2007–2008 season. New Orleans hosted the
2008 NBA All-Star Game in addition to
Super Bowl XLVII. Major annual events such as
Mardi Gras,
Voodoo Experience, and the
Jazz & Heritage Festival were never displaced or canceled. A new annual festival, "The Running of the Bulls New Orleans", was created in 2007. On August 29, 2021, coincidentally the 16th anniversary of the landfall of Hurricane Katrina,
Hurricane Ida, a category 4 hurricane, made landfall near
Port Fourchon, where the
Hurricane Ida tornado outbreak caused damage. On January 1, 2025,
a truck attack occurred in New Orleans, killing 15 people and injuring 35. The attack was carried out as an act of
domestic terrorism and was committed by Shamsud-Din Jabbar. On December 30, 2025, 350
Louisiana National Guard troops were deployed to New Orleans as part of wave of
recent nationwide
National Guard deployments. ==Geography==
